1.Progress of Survivin gene in cancer
Cancer Research and Clinic 2013;25(9):640-642
Survivin is an apoptosis inhibitor and plays an important role in the development and progression of cancer.It is undetectable in normal adult tissues,but has been showed to be overexpressed in various cancers and has been regarded as a marker of malignancy.And the promoter polymorphism of Survivin gene is closely related to risk of cancer and gene susceptibility,this might provide clues for further elucidation of the correlation of risk of cancer and genetic polymorphism,and for diagnosis,prevention and screening of cancer gene.

Objective To observe the expression of core-binding factor ?1 (Cbf?1) in aging osteoblast, and try to provide new mechanisms of Chinese medicine on bone formation. Methods Rat osteoblast from different age donors (6 months and 16 months) were isolated and cultured by the tissue-fragment-migrating-growth method. The biological characteristic was observed by phase-contrast microscope and identified with mineralizing nodule staining. The expression of Cbf?1 was examined by RT-PCR and immunohistochemistry. Results RT-PCR and immunohistochemistry showed that the expression of Cbf?1 was upregulated by Gubenzhuanggu and Jinkuishenqi, and downregulated by Zhibaidihuang in aging osteoblast, but the effect was different on the Cbf?1 expression in Bushenyijing. Conclusion Buyang Chinese medicine among Bushen Chinese medicine promoted bone formation.

Objective To probe the cause,clinical and imaging findings of children's congenital pyriform sinus fistula (CPSF). Methods Clinical and radiographic data in 23 patients with children’s CPSF were analyzed retrospectively which were confirmed by pathology.Results 1 6 patients represented repeated swelling and pain in left anterior neck,6 of whom were misdiagnosed as thyroid abscess and suffered surgery.7 patients represented masses in left anterior neck.Ultrasound showed all patients with diffuse en-larged thyroid gland with uneven mass and separated liquid dark space or infection in deep neck soft tissue,and no CPSF was identi-fied.The subsequent esophageal barium meal confirmed the fistula in 8 patients,and other patients underwent further CT scan with image post-processing.CT showed clear fistula in 4,suspicious fistula in 7 and no fistula in 4,All fistulas were confirmed by the pa-thology.Conclusion The combination of ultrasound,esophagogram and CT with image post-processing can improve the diagnostic sensitivity and accuracy of CPSF.

Objective:To compare the efficacy and adverse reactions of omeprazole and pantoprazole in the treatment of patients with peptic ulcer bleeding. Methods: Totally 362 cases of peptic ulcer bleeding were randomly divided into the control group and the observation group with 181 ones in each. The control group was treated by omeprazole 40mg in 0. 9% sodium chloride injection 100ml, ivd, bid, and the observation group was given pantoprazole 80mg in 0. 9% sodium chloride injection 100ml, ivd, bid. The treatment course was 3-6 days. The times of vomiting and melena, bleeding situation and bleeding stopping time in the two groups were observed and recorded, and the clinical efficacy, adverse drug reactions during the treatment and the expense of the two groups were also compared. Results:The bleeding amount on the first and third day in the observation group was significantly lower than that in the control group (P < 0. 05), the average bleeding stopping time and the average times of black stools and vomiting in the observation group were also significantly lower than those in the control group(P < 0. 05). The effective rate of the observation group was 92. 27%, that of the control group was 90. 61%, and the difference was not statistically significant (P >0. 05). The average daily cost of the observation group was significantly lower than that of the control group (P <0. 05). The difference in the incidence of adverse drug reactions of the two groups was not statistically significant (P > 0. 05). Conclusion:The efficacy of omeprazole and pantoprazole in the treatment of peptic ulcer bleeding was similar with high security. However, pantoprazole may reduce the times of vomiting and melena, shorten the bleeding time and decrease the treatment cost.

Objective To investigate the characteristics of HBsAg and HBcAg in combination pulsed monocyte-derived DCs(MoDC) derived from patients with HBV-associated hepatocellular carcinoma(HCC).Methods MoDCs were generated from 20 HBV-associated HCC patients,and pulsed with recombinant human serum albumin(rHSA)as conDC(control DC),or pulsed with HBsAg andHBcAg in combination as scDC.Phenotypic patterns of MoDCs were characterized by flow cytometry,and the levels of cytokines releasedby MoDCs were analyzed by ELISA,and frequencies of IFN-γ-producing antigen-specific autologous T cells were measured by Elispotassay.HBV-specific CD8 T cells proliferation was determined by pentamer staining.Results 1.The levels of MHC and costimulatorymolecules expressed on scDC were significantly higher than those on immature MoDC(imaDC)in two groups,and the levels of MHC andcostimulatory molecules expressed on imaDC,conDC and scDC in HBsAg+,anti-HBe+,anti-HBc+patients(1-4-5 positive group)were significantly higher than those in HBsAg+,anti-HBc+patients(1-5 positive group);2.The levels of IL-12 and IL-10 produced byscDC were higher than those produced by imaDC and conDC in both groups,and the levels of IL-12 produced by imaDC,conDC and scDCin 1-4-5 positive group were higher than those in 1-5 positive group.3.The frequencies of IFN-γ-producing T cells induced by scDC werehigher than those by conDC in 1-4-5 positive group.4.scDCs from 4 cases of HLA-A2+patients in 1-4-5 positive group could induceautologous T cells to generate HBVcore18-27-specific CD8 T cells.Condusions HBsAg and HBcAg pulse in combination couldsubstantially reverse the impaired function of MoDCs in HBv-associated HCC patients,and boost MoDC to induce HBV-specific T cellsresponse,especially in HBsAg+,anti-HBe+ and anti-HBe+ patients.

Nuclear factor κB (NF-κB) is an important cellular transcription factor. The important role of NF-κB-mediated cell signal transduction pathway in apoptosis is a hot topic at home and abroad. In order to discover new regulators in NF-κB signaling pathway, a high-throughput cell-based screening model based on dual luciferase reporters system was established, a number of genes that can activate NF-κB signal pathway were obtained by screening of 439 novel function genes. Among them, TMEM9B can obviously activate NF-κB signaling pathway. Further experiments showed that TMEM9B activated NF-κB signaling pathway in a dose-dependent pattern. Western blotting and EMSA experiments confirmed that TMEM9B can promote the degradation of IκBα (a cytoplasm inhibitor of NF-κB), and cause NF-κB shift from the cytoplasm to nucleus. At the same time, flow cytometry result demonstrated TMEM9B can induce apoptosis in HEK293T and HeLa cells. In short, a stable and effective screening system for NF-κB has been established, through which TMEM9B was identified to be able to significantly activate NF-κB signal transduction pathway and thus cause cells apoptosis.

Objective To study the effects of psychological rehabilitation in the treatment of paraplegic patients with spinal cord injury (SCI).Methods A hundred paraplegic spinal fracture survivors were divided into a research group and a control group with 50 cases in each.Systematic rehabilitation was given to the patients in the control group,while this was combined with individualized psychological rehabilitation protocols for the patients in the research group.The daily treatment lasted 10 weeks,6 days a week.All of the patients were assessed with the Barthel index (BI),a functional independence measure (FIM),the Hamilton depression scale (HAMD) and the Hamilton anxiety scale (HAMA) pre-treatment and post-treatment.Results Before the intervention there was no significant difference between the 2 groups in any of the assessments.After ten weeks the average BI,FIM,HAMD and HAMA results in the research group were significantly better than those pre-treatment and also significantly better than those in the control group.Conclusions Psychological rehabilitation can distinctly improve the functioning and psychological state of paraplegic patients after SCI.
